Support AppVeyor

[giggio]

AppVeyor is a very nice .NET/Windows CI Server:
http://www.appveyor.com/
And it already works with Coveralls. Here is an example build with AppVeyor, using Coveralls.NET:
Build:
https://ci.appveyor.com/project/code-cracker/code-cracker/build/1.0.0.303
Coveralls site:
https://coveralls.io/r/code-cracker/code-cracker
Source is here:
https://github.com/code-cracker/code-cracker/

I am not sure what is needed to have a supported CI server on Coveralls, but as it is already working, you might want to include it.

Hi all, good call -- I've added http://www.nuget.org/packages/coveralls.io to our docs and listed AppVeyor to our supported CI's.

Thanks!

@nickmerwin Does this mean that Coveralls will be able to comment on PRs when the build happens in AppVeyor?

[nickmerwin]

@giggio it's possible, but I'm not sure that integration library supports it, although it would be trivial to add.

From Appveyor's docs (http://www.appveyor.com/docs/build-configuration):

APPVEYOR_PULL_REQUEST_NUMBER

Our API docs (https://coveralls.zendesk.com/hc/en-us/articles/201350799-API-Reference) show how to associate a build with a PR using this post parameter:

service_pull_request

Multi-job builds do not appear to group reports together.

I had to add an env variable to make it work: #888 (comment)
